lidingWhy do professionals choose LIDING flange machines?
One machine does two jobs, cuts your costs in half
No more buying two separate machines for PDF20 and PDF30 flanges. This single unit switches between the two sizes in minutes, saving you thousands of dollars in equipment costs and precious workshop space. It’s the most cost-effective solution for mixed-batch duct production.
36 precision rollers make perfect flanges every time
We use 36 sets of precision-machined Cr12 steel rollers, heat-treated to HRC55–57° for maximum wear resistance. The multi-stage forming process ensures flat, straight flanges with tight, leak-proof joints. No more bending, no more rework, no more wasted material.
Built like a tank for nonstop daily use
This machine is overbuilt to handle 8-hour nonstop production. The 40mm thick solid side plates and heavy-duty frame eliminate vibration and shaking. The 45# steel quenched spindles and high-quality bearings run smooth and quiet, with minimal maintenance required.
Dead simple to operate, no fancy skills needed
The control panel is straightforward with just three main functions: forward, reverse, and emergency stop. Any worker can master it in 15 minutes, no special training required. We also include free wearing parts with every machine and provide lifetime technical support.
